    "No smell, no weird texture, clearly largely water based, perfect. After years of using Minoxidil, i kept losing my hair, and had those well known bad side effects on my skin. No side effects at all with the this."

Reviews Summary
Customers say this scalp treatment shows promising results for many users. Many reviews mention seeing baby hairs and reduced shedding within a few weeks to months of consistent use. The lightweight formula absorbs quickly, though some note it can leave residue that requires morning washing. Reviews are mixed on texture - while some find it non-greasy, others mention flaking or buildup. Most users emphasize patience is key, with noticeable changes typically appearing after 2-3 months of regular application. A few report scalp sensitivity or irritation.

    To replace 5% minoxidil associated with dermapen

    Hi, i'm a 50 yars old man with androgenetic alopecia.

    6 months ago, i've switched my routine from:

    - Dermapen 1.5mm once a week + minoxidil 5% twice a day

    To:

    - Dermapen 1.5mm once a week + Inkey hair growth twice a day

    The Inkey product is really reassuring, no smell, no weird texture, clearly largely water based, perfect.

    After years of using Minoxidil, i kept losing my hair, and had those well known bad side effects on my skin.

    No side effects at all with the Inkey product.

    After 6 months of using Inkey hair growth, I can't tell the difference, my hair seems a tiny bit thicker, i guess the dermapen + Inkey product kind of works, but that's barely visible.

    It seems that i stopped losing my hair, which is already good, i guess.

    Nevertheless, i bought 9 bottles and will keep using it, because it seems to have some positive effects, and most likely because it has no side-effects!

    Also, despite what i've read, you don't need to clean your hair in the morning, if you have short hair you could even use it as "hair-gel" to comb your hair, it's perfectly fine!
